Tutkimuksessa käydään läpi allianssin teoriaa, allianssin saavutuksia ja asuntotuotannon erityispiirteitä. Näistä kolmesta osasta muodostetaan allianssimalli asuntotuotantoon. Allianssimallia testataan teemahaastatteluiden avulla. Teemahaastatteluista kerätyn aineiston avulla allianssimallia kehitetään. Tutkimuksen tuloksena on saatu allianssimalli, jota voi soveltaa asuntotuotantoon.Building project has many parties and their goals can be in conflict.
